SEDIMENT OR SAND TRAP.

SPECIFXCATION forming part of Letters Patent No. 552,877, dated January 7, 1896.

Application filed March 21, 1895. Serial No. 542,720. (No model.)

To all whom it may concern.:

Be it known that I, GEORGE IPSON, a citizen of the United States, residing at Hunting-A ton, county of Emery, and Territory of Utah, have invented a new and useful Mechanical Device known as a Sand or Sediment Trap, the objects of which are to cause moving par ticles of sand or other sediment in canals or other Water-ways to settle at a given point and from there be discharged into a drain or ditch, of which the following is a specification.

I attain these objects by the mechanism illustrated in the accompanying drawings, in whichd Figure l is the ground plan; Fig. 2, a lon- Fig. 3 is a cross-section on the line 3 4, Fig. l, and Fig. a is an enlarged section of the discharge valve or gate at 5 on the line 3 El, Fig. l.

Similar letters refer to similar parts throughout the several views.

The letter A, Figs. l, 2, and 3, represent the banks of a canal; B, Figs. 2 and 3, the bottom.

There is a pit dug in the bottom of the canal the sides of which slope toward a common center C, Fig. 1. These sides are lined With stones and cemented to make a smooth surface. This forms a trap into which the movin g sands or other sediment Will settle.

At the point O, Fig. 3, there is an opening for the discharge of sediment into the drain D, Fig. 3. This opening is provided with an iron or other metal casing E, Fig. a, which forms a seat for the valves F F. These valves are made of metal or other substantial material and made to iit the seat E and are connected by a shaft or rod G, which extends above the canal-banks A. The upper end of the shaft Gis provided with a lever H or other suitable device by which the valves may be moved np or down. When the valve F is closed, Fig. E2, the sediment will settle in the trap. By raising the lever Il, Fig. 3, the valve F will open, and the sediment will be discharged into the drain D, which leads to some point lower than the drain-inlet.

The form of the trap is such that the discharge is at or near the center of the canal, and having sloping sides the sediment seeks the point of discharge by gravity. 'In case of freezing the sloping sides Will prevent daniage from expansion.

The shape of the valve F F is such that the discharge of sediment is perpendicular and Will afford a free and sure exit for the sediment. l

The valve F is provided with two seats, one at the upper and one at the under side of the discharge-opening C, and are designed to crush or break up any sediment that may collect above the discharge-opening and become hard. This is accomplished by Working the lever H up and down, which causes the valve F F to open and close alternately and to reduce any lumps of sediment that Would prevent a free passage through the discharge-drain.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination in a sand trap of an oblong pit, the sides and ends of which slope down- Ward toward a common point; said pit having an aperture the full size of the bottom of the pit with a metal casing E stationary on the sides of the aperture; crushing valves F, F, adapted to make contact with casing F., shaft G, and lever H, adapted to operate the crushing valves F, F, substantiallyT as and for the purpose set forth.
